The curriculum analysis of lighting design course in the Interior architecture departments in American universities reveals they share a major concern in the basic lighting theories, the sorts of light source and lighting equipment, daylighting, and interior lighting plav. The curriculum is usually composed of two semesters, the first semester being about lighting theory and simple project, while the second one abut more professional fields of design studio. The curriculum of lighting design at the Interior architecture departments in Korean colleges and universities usually consists of introductory courses in the field. Almost every institution allocated only one semester for the courses, and as the courses should cover the broad range within a short time, they were lacked in the required depth and systematic approach. The analysis also reveals the curriculum in Korea puts emphasis on the interior lighting equipment design, while disregarding the importance of daylighting. In comparison, American institutions have their curriculum focused upon the use of daylighting. The curriculum of lighting design courses in Korea, a major part of space rendering methods in the field of Interior Architecture, should be improved without delay. The courses should be included in the required subjects and the educational aims should be changed from offering a general understanding of the concepts to providing professional knowledge and skills, which would contribute to the competitiveness of the departments.

Nighttime construction is being adopted by many state DOT's as a way to mitigate the impact of construction operations on the traveling public. Although a number of states have developed standard specifications for nighttime lighting, these standards are usually in the form of generic requirement statements that only specify minimum illuminance levels. The lighting standards do not include specific ways to achieve this illuminance level such as lighting arrangements and configurations for various work zone plans and construction operations. This leaves confusion between the traffic engineers and the contractors and does not guarantee consistency in those plans, thus affecting productivity and safety (lighting conditions account for 18% to 28% of work zone accidents). The main objective of this study is to utilize three dimensional animation and lighting analysis software to study and model lighting conditions of a construction site. This is expected to increase the safety and productivity of construction operations by achieving consistency in work zone lighting schemes. A computerized model was developed, called Nitelite. Various lighting schemes can be studied using the software to provide for typical applications including lighting fixture's locations, luminance, mounting height, tilt angle, and fixture type. The results from the developed software tool were validated through comparisons with previous research conducted using field measurements.

Low road lighting is a lighting device that complements the shortcomings of existing pillar-type street lights. It is a lighting device that emits light from the side of the road surface and adjusts the luminance of the road surface like a light carpet. In this paper, to achieve full commercialization, we analyzed the luminance of the installed road surface and studied whether lighting could replace existing road lighting. In this study, the LMK (Luminance Measurement Camera) LABSOFT program was used to measure and analyze the surface luminance of road lighting, and the RELUX program was used to evaluate and analyze the simulation performance to determine light-based lighting conditions. A study was conducted to determine whether replacing pillar-type road lighting with low-level road lighting in a real environment would ensure comfortable and safe night vision for drivers at night.

Recent high oil price results in the development of energy saving technology such as LED lighting system. Street-lighting system using COH LED package can save energy because the heat dissipation through cupper base is better than conventional technology. Studies on manufacturing processes of lighting system are insufficient even though LED package design and its heat analysis have been studied. This study focuses on the problem and solution of manufacturing processes such as LED packaging process, optimized emission angle, and LED bar dimension for mechanical assembly. As a result, we established better manufacturing alternatives of LED packaging and street-lighting system with higher lighting efficiency of 84 lm/W, as well as good illumination intensity of 39.7 lux at 6 m from lighting source.
